[Early Cuyler]

"Gravity" is somewhat of an abstract concept when you can maintain neutral buoyancy in your "atmosphere" (in this case: the ocean). It's easy to weigh a lot when you don't actually have to support all that weight _with your body._

[Jean Alonzo]

MN h ju

[niceyourss]

john mayer’ed

[Baguette with cheese]

Fish have organs that fill with air for them to go up and deflate to sink.

[Early Cuyler]

@Baguette with cheese Sure, but their _experience_ of gravity would be totally different. Humans tend to think of gravity in terms of things going down. A fish - being more concerned with buoyancy in any case - would probably think of gravity in terms of things going up.

[quoc lien]

buoyancy, i wonder how high can u reach into the skies and drop a nuke into the ocean, how deep it can penetrate before buoyancy affects it from going any deeper then detonates, whats the impact or reach the blast can go further down the ocean..i wonder if any of that is ever measured?... i assume a missile shot downwards in the ocean is no different to a submarine diving to the deepest depths that bouyancy and pressure stops it from continue to dive down?

[Luke Sterling]

When I was a child, my parents took me with them on a family vacation to Tahiti. In the airport, my dad got me a book from a newsstand that was an illustrated dictionary of sea creatures. Surprisingly, despite being a book meant for kids, that dictionary contained a vast array of ocean animals that most people have never even heard of. Both the Greenland shark and the vampire squid were in that book, and I still remember them from reading it all those years ago.

[Renks]

You should have taken Dutch and his plans with you to Tahiti as well

[LlahNitram]

@Renks you beat me to it😡

[Mr.PlagueDoc]

@Renks got me giggling

[Zeravack]

You’ve made dutch sad

[Luke Sterling]

@Renks Y'all are referencing something I either don't know or forgot about lol. What's this about?

[Mohammed Mustafa]

I was expecting some aggressive creatures. But this is still fascinating, plus the narration is soothing.

[smh tbh fam]

Yeah I love her voice

[Henry Rooyakkers]

Yes , But her voice is not verry pretty especially one the end of a sentence.

[Kami Tenchi]

@smh tbh fam it's piercing the ear, need a deep calming voice, Attenborough esque

[tink]

@Henry Rooyakkers weird thing to say

[Chronx100]

13:45 "Relatably, when giant isopods find a significant food source, they gorge themselves to the point of compromising their locomotive ability." Damn, ive never felt so similar to isopods in my life. Thank you narrator.

[Laura Lyon]

Ewwww

[Errortrossity]

Why take one slice when, you can swallow the entire cake?

[Rockoyhead]

dont overeat boii

[CJ]

Sometimes we just 🍃😮‍💨 and eat too much man

[AYUBALLENA]

@M Y T H I C A L N O V A did the dog not give you enough attention?

[Icommittedarson]

Fun fact: most (if not all) magnapinna squids have been juveniles, using the scale of objects that they’re often seen by, such as Oil Rigs, have been 20 - 25 feet long, meaning the Magnapinna Squid are certainly longer than we’ve seen

[KARMY!!]

ABSOLUTELY! i wonder all the time how large a fully grown magnapinna squid are

[Notorious CJ]

@KARMY!! 60ft to 75ft

[KrazeM8]

New title of the video: Evolving into muslims

[galaxy guy]

You got confused by wikipedia omg. Yes wikipedia said all bigfin squids (magnapinna) confirmed are babies, the one we see in the videos are adults. They aren't babies. They are the adults, the reason wikipedia says that is because we haven't confirmed whether these *adults* are bigfin squids, the same species as those babies

[Yashwant Gurjar]

​@KrazeM8 .... What

[Christian Petersen]

From the Greenlands Shark's point of view, it had been swimming around in the deep ocean for a couple of centuries when suddenly, the water started getting warmer. Then plastic appeared everywhere. Finally, on a single day, it felt thousands of shockwaves coming from everywhere. After that, the plastic gradually went away and the water went back to normal temperature, and the greenland shark swam around for a couple of centuries more, wondering what the hell that was.

[Kelsey 23]

Did all of humanity get smited down by god? Lol I didnt get the ending

[Christian Petersen]

​@Kelsey 23 Wouldn't that be wonderful if God did it? Because it would be fair and not arbitrary. I would raise my hands to heaven and shout:" OMG, I can't believe it's you! I sorted my trash every time! I used public transportation!" And he'd be like:" Ew! Atheist! Obviously going to hell!"

[Pandy]

@Christian Petersen just claim you are a real christian. get him on the loophole.

[Steve Z]

This is comedic level material 😂

[Keely]

​@Kelsey 23 I think k it would referring to mass nuclear war, i.e. the thousands of shockwaves

[tamatebako]

I had no idea there were vertebrates that could live up to 500 years. That is incredible! Definitely need to look into the Greenland shark now.

[Embreis]

as she said, living in the cold dark waters, moving slowly, burning almost no energy, starting mating when 150yrs old and completely blind all their life because someone is nibbling at their eyes. not a particularly pleasant fate

[Inner🌟Luminosity]

Same

[tamatebako]

@Embreis I wouldn't necessarily extrapolate from our experience to those of other creatures. You could say the same thing about a mole. Isn't it disgusted having to live below ground, eating worms all day, being almost blind? Does the mole say to itself every day: Oh I wish I was a rabbit above ground, I could eat green grass all day and see the sun shining? Probably not. A mole evolved to be that way, it doesn't know anything but that life, and it doesn't have the mental capacity to envision something different for itself. I don't think it is unhappy. Having said that, the Greenland shark probably could do without the parasites, even though it doesn't rely on eyesight all that much. Still, parasites suck.

[Carrick Dubya]

@tamatebako parasites suck and so do most people we all loathe, but like parasites we need them for something - right? lol

[SSGSS Beet]

@Carrick Dubya no… not really lol

[sum sum]

I have an awful fear of the ocean whilst also being really interested in those bizarre deep sea creatures - I'm terrified but I can't stop watching (or rather just listening for a lot of it by hiding in the comments when you show ocean footage)

[N&N Games]

I feel called out…

[seonhwa 선화]

omg, same here! it's scary and amazing at the same time for me

[BLENDITE]

exactly man, its impossible to just watch forever

[poop(real)]

Dang I thought I was the only one

[scp agent rose]

act. my guys chur NOTZ alone in tis & chur purrfectwy normals the answer tu chur comments ish called thallasaphobia witch ish the fear of the deep dark ocean and wike myself as i have it 2 its a common phobia many ppl have :3

[Windowsprodukt]

The Colossal Squid somehow feels even more terrifying when you know it's not hunting. Just a *huge* pair of jagged tentacles lunging out of the darkness, grabbing something, followed by complete silence for several months.

[Jaaz7]

They're fascinating but I'd be creeped the hell out if I saw their 30cm human-like eyes just staring at me.

[Mark]

If aliens ever visited they'd likely not be arsed for us humans. They'd probably want to study the squids and deep sea creatures. They seem to be much more advanced than us

[Thomas Prent]

@Mark lol what? Squids are not the ones going to space as far as i recall, how are they " more advanced "

[Krumsmasher]

Hey new viewer here and don't comment much but just wanted to say this video is spectacular, grabbed my attention from the moment it started from the in depth descriptions to great narrative of the subject. WITHOUT constantly repeating what has been said before to simply increase the video duration. This was a spectacular job in editing and information delivery.

[nick g]

completely agree

[bA6emugEfEv]

I honestly came to the comments to type essentially the same thing you have! I am glad I am not the only one who notices the amount of effort put into these videos. And after watching a few others too, man I appreciate it. Hope they get to read this and it makes their day. Keep up the fantastic work!!! (And) yes I know my name looks spammy. Tis just for security.

[Michael Macha]

First I hear about the lower calorie need of the giant squid, and I'm like, "Oh, well that's all right, it's just chilling and looking for the occasional provident snack." Then I hear about its crazy slow metabolism, and how it only needs about fifty calories per day, just hiding down there, waiting patiently... somehow, that just made it scarier in the end.

[Orius25]

It was 40 calories per WEEK, lol

[Mims Zanadunstedt]

Two apples a day keeps the doctor away, for a month.

[Urza26]

I'd rather it sits still and wait rather than actively swim and hunt us down.

[Orange is the new strawberry]

Refreshing to actually hear a real human voice over. And so well done too! Of course, I came to see the big bad fish of the deep, but I stayed for the high quality delivery of information. Makes me want to check out more video's on the channel

[olserknam]

I'm pretty sure most videos have real human voice overs.

[Chuckie Gravesfield]

@olserknam its mostly ai

[MdMDmD]

I always wonder, if these deep sea creatures still have functioning eyes at these depths they must be ridiculously sensitive right? So would the intensity of the lights on the rovers be as bright for them as us staring at the sun?

[agamenon marques]

I thought the same, I was uncomfortable seeing the camera flash in their eyes

[Rosie Hawtrey]

Which is why most of the time they use red lights, enough for us to see, but not enough to harm the critters. White light only used for filming purposes.

[Saosaq Ii]

Which is also odd because normally evolution favors use it or lose it and there isn't enough light down there to even use it majority of the time so I would expect them to lose it But if it became more sensitive that's understandable too, but less if they simply enhance other senses and lost their eyes

[Gurgle Blaster]

@Saosaq Ii it doesn't necessarily have to be more sensitive. Although they are due to the size of the organs involved. Keep in mind they are hunting animals with bioluminesence.

[The In-Famous El Guapo]

I would not be surprised if there are depths we've yet to discover and creatures we've never imagine could possibly exist.

[L.S.]

magma worms.

[Jaaz7]

We discovery new species almost everyday. They're just not so different from already known animals.

[Jaaz7]

@Mr.Nobody.19817 yeah, it astonishes me when people say "we've only saw 5% of the ocean" or "megalodon still exists in the deep sea who knows!" as an argument. We've got a pretty good idea of what kind of animal can subside in the deep sea. Small, slow and harmless animals who bare too much pressure and probably eat once a week due to scarce food.

[Eren Yeager]

I loved this video, the message at the end was very well delivered! I wish more people realized just how amazing this planet we live on is.

[across_the_plane]

Planet??? 🤦🏻‍♂️🤣😂

[Alexander Welker]

The message at the end was preachy and unscientific, the delivery leaves a bitter taste behind.

[Dcookies100]

@Alexander Welker talking about how we're destroying our planet isn't unscientific or preachy. it's a literal fact. if you don't like hearing about it, too bad.

[Dcookies100]

@Alexander Welker I'll respond to the last portion: yes I agree that we should focus on figuring out how to manage our waste and we should definitely ditch fossil fuels for nuclear energy. Plastic usage also needs to be focused on. Even just doing this three things would vastly, vastly improve things.

[Aikira Beats]

It's pretty cool seeing how big these animals can get. I've always wondered how these sea creatures thrive in such harsh conditions.

[im a box head]

You forgot to mention the fact that the crustacean that digs into the Greenland sharks eyes acts as a lure so that the Greenland shark gets easier meals even though it makes them completely blind it truly doesn’t change much because the zone they live in receives so little light it doesn’t change really anything for the shark

[Jytali]

Could you imagine we somehow were given the slow metabolism and long lived life as the Greenland shark, we’d be able to travel space more realistically. Actually gives me an idea to make a space creature or race that’s similar

[boo314]

Interesting thing is that in so low temperatures many chemical reactions are slower or non existing. That would suggest that those creatures not only live longer but they are living slower. I bet that such a gigantic pressure also adds to this effect.

[bern_stock]

If the aging is slower, then does this mean a reproductive cycle's length is larger? Then does this mean that they did not undergo too much of an evolution? Then does this mean that birth of life on earth can be traced back from them, cuz you know the should've survived meteors and stuff? Then are the prehistoric?

[boo314]

@bern_stock that would be the natural conclusion. If I recall correctly Greenland shark reaches sexual maturity at age 150. So indeed EVERYTHING is slower.

[Sukhvir Jhajj]

Hahahah oh common man..u also live under water and all of us..its our soul..and by the way birth and death only happens with the command of the almighty supreme lord...everything happens with lord’s command..its hard to digest this talk but its reality the truth..and if u wanna know this by yourself then look inside u(spiritual heart,space),like where our consciousness rest during sleep,over there when its stay conscious or awake then u gonna find all the answers..even which science never ever gonna get..

[boo314]

@Sukhvir Jhajj I would suggest to take a look more into engineering books than new age. It is possible for every system (yes, biological too) to just shutdown and be on stand by. This is what dreams are. You do not remember all your dreams. It does not mean that you do not dream every night. This is where your consciousness goes

[Francisco Reyes]

@Sukhvir Jhajj there is no God, only Glibbus the Crab

[Severine The Panda]

I really enjoyed this video. It was really interesting and informative. I also liked you segway into Morning Brew; the bit about the greenland shark being onto something hit pretty close to home. I don't think I'd mind living in deep dark oceans with parasites on my eyes if it meant not having to live in a world that's on fire.

[Kristopher Driver]

This KZbin video is better than most documentaries I've seen anywhere over the last few years. So well done, thanks for uploading 👍

[WorldWeaver]

Thank you for making this video! I love that it shares cool facts about the ocean in a not-horrifying way and tells people that we need to save it! :D

[Errortrossity]

Personally I love the deep sea, I am really intrigued and captivated by the otherworldly biology of the creatures down there, I want to know what kind of creatures live down there, and how they survive in such a harsh deep sea wasteland, I want to experience firsthand what being in a submarine down there feels like, I want to be one of the first people to go to the bottom of the ocean and poke a snail fish with my finger because I felt like it, also, the giant isopods are adorable.

[7200itnoel]

despite all these scary creatures, damn, the ocean is still so beautiful. Knowing that all these rare lifeforms are in there, just lurking around, is just too mindblowing. Looking at the ocean from the surface, and understanding how incredibly deep and dark it goes below... its just so.. amazing. Gaah. cant even explain how awesome the ocean is.

[poo]

Imagine if the Sea Creatures had their own city and language and we are basically aliens to them making them tell stories of mysterious objects that had blinding lights go down and observe them for hours

[Logan Morales]

So SpongeBob?

[Tom Cruz]

Giant Squid: "I swear bro I was abducted by aliens from those ships with weird lights. They took me up there and experimented on me!".

[The Siamese]

And yet we still see human out there fishing (I’m not talking about the ones who live as fisherman or fish monger) , laughed about it, posted it online because while the fish is dying, didn’t even count the fact that it got hook on their mouth i also heard about the fact and that people talked about dolphins are literally human but live in the ocean, rape, torture, play with their prey etc.. Now that I look back here at us, I can’t look at those people the same way anymore

[scrublord]

dont the creatures communicate by using flashing lights from their body

[bedrock30_]

@Rkkz Dude this is a video on the ocean-

[Shaga Matula]

Really interesting thanks very much for doing these, very informative (From Wexford, Ireland). Just one question is the shark you mentioned the longest living animal on the planet? Or is or was there another longest living animal. Great voice, well done with the narrating can’t be easy.

[Linda Isherwood]

Makes me think about the best calamari ever! All joking aside, Nature never fails to fascinate! Colossal squid is amazing. Excellent presentation. Thank you very much.

[James]

best calamari ever LMAOOOO why did that make me laugh so much 😹😹😹😹😹

[Oberon]

Stephanie Sammann's narration is absolutely perfect, such a sweet voice and calming. Thank you for the narration :)

[Jeff Again]

I'm still trying to grasp the fact that there are fish 500+ years old. Were scientists to put strong focus into researching the properties that enable them to do so, we may find info that could extend our own life expectancy. The "lowered metabolism" I suspect has a strong part to play. Great video, thanks much!

[The Lone Fedora]

This is the exact topic I wanted this channel to cover ever since I discovered it a year and a half ago, thank you for covering some of my favorite creatures that swim this planet with us. Keep up the wonderful work!

[Rizwan Fariz]

This is my favorite topic too

[whatharmcanitdo]

The "Natural World Facts" channel also has an interesting video about deep see gigantism among other fascinating subjects. Although this video is more complete

[Nen Master5]

@Rizwan Fariz Science is nice, buuuut... I see Disinterest. Im sorry to see many not much interest in being Updated, let alone fighting-back against Extremism. I fear not many people even watched the video 'Marjorie Taylor Greene Has DEEPLY Disturbing Views'.

[bryan ramirez esquivel]

O

[Bauso, Bong bong Ryan]

😱

[Bernie Schattka]

Absolutely fascinating! Thank you Real Science for producing videos like this.

[Daniel Verberne]

Excellent video - really appreciate the usage of metric measurements. My sole criticism is minor - that various scenes depicting the giant/colossal squids in CGI aren't clearly called out on screen as being CGI. I'm able to differentiate between the real footage and the generated stuff, but it's not always obvious so a sign on screen making it clear is always useful.

[SCENIC MUSIC VIDEOS]

I use to have aquariums and I noticed that the same fish when placed in a large aquarium tank grew much larger than the same one in a smaller tank. Could be one reason some grew to enormous sizes .Also the amount of oxygen in the tank can make them grow much larger.

[Clazziquai R]

That was amazingly well done and super informative, loved it

[Bernard Putersznit]

Thank you - loved the science you unveiled to me - in particular the enzyme boost at deep depths - who knew? 🙂

[Christopher LaHaise]

The thing with the Greenland Shark is that they swim into freshwater to shake off the crustaceans - they've been found in the rivers of Quebec, having swam up the seaway to get there, and have been found in the lochs of Scotland. The freshwater lets them shake off the crustaceans, and then they swim back into the sea. They're really, really strange.

[Laura Smith]

They make me want to just pick them off. That can’t be comfortable to swim with. I guess evolutionarily speaking, when you have no need for eyes, eye parasites are more of an annoyance than a death sentence

[Leo M]

#gogglesforgreenlandsharks

[Laura Smith]

@Leo M Finally, a hashtag I can get behind

[Ricey Boi]

​@Laura Smith fr, I support this

[Kelci]

I was falling asleep while listening to this… and it was terrifying! The narration is so descriptive and detailed! Great video 😂 I definitely had to wake up and see what was going on!

[Indie Rio]

😂 this happened then I read this comment once I woke back up

[Ravioli Anth0ny]

When she started talking about how little food colossal squids need, I had to check to make sure the sources were reliable. That’s so amazing!! It seems unreal

[Nathan Fankhanel]

The giant squids remind of the prehistoric Tusoteuthis which was a giant squid with next to no predators that lived at large depths. Maybe these are more like the prehistoric ones rather then the squids we find common today

[Whimsically Widdershins]

Monterey Bay Aquarium has a deep sea exhibit! They mostly have various types of jellyfish, but they also have the Giant Japanese Spider Crab, they have siphonophores, some very deep water fish and I got the pet a giant isopod! It's very very cool and its a must-see!

[GabrielleT]

Love that nature can produce some real life lovecraft!

[Daniel L]

The Greenland Shark is my personal favorite shark and fish in general. Their incredibly long lifespans gives them a sense of agelessness. To think there probably are specimens older than the majority of nations today is simply amazing. The eye parasite sucks admittedly but they seem to get along just fine so who am I to say nay?

[S I D E W I N D E R]

I can agree, they are really cool sharks, and are also in my top 5 favorite fish. My favorite fish has got to be the gulper catfish though, as they have such a unique biology, and they look like they belong in the deep sea, even though they reside in the rio negro. Gulpers are so unique, as they can eat fish twice their own size, and they are able too because of their expandable belly, much like an angler fish. They are also very strong and of course, nocturnal… i guess that’s why they remind me of a deep sea creature so much. I actully had a gulper catfish, and he was my first fish. I was so fascinated by their biology that I spent hours just watching him swim around. Also, it is so interesting How Greenland sharks live up to 500 years or more, though. I’ve heard of some that have lived till 700!

[moderndemon84]

Beautiful world I mean,you can feed a lot of people with them.

[SoupyMittens]

Beautiful world but I mean there definitely aren’t enough of them to go around eating them

[Joel Miller]

@moderndemon84 Lol or you can just become a snack for it 🥶🥶🥶

[moderndemon84]

@SoupyMittens You never know,there might be enough for everyone.

[Illfection]

this is so awesome. i actually love thinking about how much of the earth is unexplored to us. i think octopus will become the next dominant species after we all drown. them or dolphins

[Nick Goutz]

The interesting thing about the crustacean latching onto the Greenland sharks eyes is that while they do make it blind, the crustaceans actually produce bioluminescence which attracts small animals that the shark will feed off of since anything that is small enough to consider those little crustaceans prey is gonna get eaten by the Greenland shark. So it’s a form of mutualism/symbiosis where the Greenland shark trades one or both of its eyes for better chances at food. Keep in mind that sharks have an excellent sense smell as well and the blindness doesn’t seem to be as much of a negative anymore

[L3x1x0n]

I have to say one of the best I've seen. Quality information. I remember some stuff about arthropods, why? because was lucky enough to live that have away secrets. We found trilobites. And as you say in your commentary. It's a giant wood louse that you find in your garden. Very fun and PhD level science. You get an opposable thumbs up.

[Laquan Lewis]

This is amazing of all of this life deep within the oceans. That was tremendous. I give this video a perfect 20. Makes me want to go into the abyss of the ocean, I wish to see all of the ocean life that lives far down. And to know that life existed so far below is intriguing as well

[FatefulWaffle]

I have both a deep fear and respect for the sea. I'll gladly swim at the beach, but I know that the ocean is an unforgiving mistress that could sweep me away if it felt like it

[Willem van de Beek]

I wish they did more deep sea research for you to report, this was fascinating! :)

[John Chance]

Me too. It annoys me that we don't get more info on cold seeps, black smokers, hot springs in the ring of fire, life under the ocean floor . . . There are so many energy sources down there, and then we have stuff drifting down from above as well, your marine snow, driftwood, whalefalls . . . and most of it is in places we haven't gone, or can't go.

[Carrick Dubya]

@John Chance gotta be careful because the earth might split open when people start digging to far down and cause a real disaster like the 2012 movie . . .

[KaucionDaBoss]

We wasting time in space when the deep sea has all the answers

[Alaric Balthi]

@KaucionDaBoss We should do both. Researching both will drive humanity forwards (space research is expensive and very long term investment, ocean is cheaper and shorter term) and i hope that as time goes by, we as the nr. 1 reason of the destruction of the world, will mature enough before starting to do any serious work in the ocean so we would not destroy it more. Had humanity have the ability to mine the ocean floor 50 years ago, there would be absolutely nothing left today. Even today we have some chance to work down there with tolerable damages and in the future hopefully with zero or miniscule damages.

[Kent Le]

It’s just so fascinating to think about the deep sea, and the mysterious phenomena lay beyond!

[Siva]

Brilliant presentation, my gratitude to the creators. I could not connect with the 'climate change' angle at the end. We ought to respect these creatures more. They have survived the harshest conditions to be here, petty human activity on the distant surface is not going to stop them. We'll be gone, and they will be here long after us. We must aspire to place ourselves beyond the human centric pinhole when we contemplate the Universe. Morning Brew pitch at the end worked like magic, never have I signed up to a KZbin ad plug so instantly 🙂

[stars]

i definitely want to be reborn as a greenland shark in my next life :") this is a great video!! thank you for all the cool info

[mosy]

I'm so impressed with the video taken in such deep sea. Are those drones or something?

[Christian Young]

This is an exceptionally well done video.

[Hmm]

Thank you for releasing this for FREE. Maybe ten years ago, it was tough to get this kind of quality on products that are released freely to the public. Could you cover more of the genesis of the squid and maybe its prime age? The age where it was most abundant and diverse. I know it's probably not as easy to cover something like this because they are soft-bodied but are the beaks different enough from each species that we can tell species apart and maybe guess its behavior?

[Clive D'Souza]

10 years ago KZbin had more documentaries available for free.

[Hmm]

@Clive D'Souza there is a difference between pirated and things like this video. Sure you are getting to watch them both for free but this content was meant to be free. There is a difference in intent.

[Josué Caleb]

This might seem free to you, but they do get paid in ad revenue

[Hmm]

@Josué Caleb reeeeeeeeeee. No one is saying they aren't getting paid. Its not behind a paywall like Netflix or any other paid streaming service. Please read before you write.

[Josué Caleb]

@Hmm I repeat the same back to you. Nothing is free on KZbin, the paywall is your data and adsense

[Ina]

It would be terrifying to think about the possibility of the animal kingdom beginning a transformation of increased size.

[SpookyRumi]

Amazing video! I didn't know greenland sharks could live that long

[Willius Caesar]

As a thalassophobic I like to think the reason so many deep sea creatures are bigger the deeper you are is the closer proximity to hell itself, thus filling them with unholy power and strength

[lightningboltt543]

Its unbelievable that the moon is better explored than the deep sea

[fab 555 Trainspotting & more...]

Its crazy to think that we know more about the universe than the deep sea

[Hussain]

This channel covers the EXACT topics that randomly come to my mind and ends up answering all of them! Looking forward to this channel hitting milestones one day!!

[Maxwell]

They could be better

[D.O'D.]

Absolutely Amazing! I'm without words...No, in giving this more thought I would have to say that the view and the amazing (there's that word again!) assortment of life 'down there' can only be surpassed by the expert dialog of the narrator - great job!

[wolverine]

i like how you explained how they calculate the sharks age,keep up the good content

[HewieSux]

this is why Subnautica was a beautiful horror game for me and fantasy space creatures or the old ones are more of a concept . the only thing more terrifying would be, if the deep sea would hold clowns

[Astræus]

It's similar to the also counter-intuitive occurrence of island gigantism. In an environment where resources are scarce and living is tough, you wouldn't really expect creatures to become larger than normal, you'd think they'd become smaller to suit the environment more.

[Obscure]

Fantastic video and writing, thank you for the immense effort.

[Bauso, Bong bong Ryan]

Yeah thanks to Him.

[jhors]

Eric, very informative, thanks so much for posting this!

[Chris Odom]

The quality of this channel cannot be overstated. It's a shame that this type of content isn't the top trending on KZbin!

[prateek priyadarshy]

People are mostly watching tiktok😂. That's what youtube algorithm shows.

[Chris Odom]

@Tim Sullivan not a shill, just a guy on the internet 🤷🏼‍♂️

[Tim Sullivan]

​@Chris Odom Said that because your articulate comment was at odds with the judgment it revealed. -That is a joke of a channel - my point being that it is SO bad that I found it unlikely that one who could express themselves as you had could be so seemingly oblivious to that (imo) glaringly obvious fact. Anyway - sorry and feel free to enjoy what you choose.

[Tim Sullivan]

@Chris Odom Just to explain a bit further - these type of channels are made with all kinds of stock of pretty stock footage loosly stitched together by a script written by unqualified amateurs. For instance - apart from the species mentioned, the extreme depths do NOT tend to foster gigantic creatures - in fact the exact OPPOSITE is true. - at extreme depths most animals are relatively tiny. The unmanned submersibles that collect specimens rarely snag anything over a few inches long. Huge creatures are much higher up in the water column where they can find he more plentiful food supplies their bulk requires. But iof you just look at the entire presentation, they say nothing you couldn't come up with after reading an entry in an encyclopedia. Fraudulent crap. ] PBS has tons of free quality science material on KZbin. Take care and sorry for that comment ;-)

[my infinity]

Very interesting. I am fascinated by the sea and all of it's life that lives in it!.... thanks!

[X Crockery]

The Oarfish lives at depths of 200m-1000m, not in the trenches. Same with the Giant Spider Crab which lives at 50m-600m depth. The big red jellyfish lives to a maximum depth of 1500m and the Greenland Shark lives down to a maximum of 2,000m, but only in the tropics - in its Arctic habitat it lives close to the surface.

[The Critic]

Amazing. 😊It seems the deeper we go, nature had evolved and adopted to our planet's changing environment.

[HealthyTalk]

Loved the documentary. Clear, informative, and high quality.......

[Princess Skye]

You would think harder conditions makes it harder to survive… so it truly is amazing that it’s even possible.

[Unfinished studios]

The deep sea creatures are my favourite animals just because they’re so unique and cool and some people believe that some of these creatures would exist and another thing I love about deep sea creatures is that they have to adapt and try to find different ways to get food and survive!

[Early Cuyler]

Anybody who enjoys this would also enjoy the "Children of Time" series by Adrian Tchaikovsky (specifically book 2). Sci-fi; speculative biology, forced evolution, huge cryogenic induced time-skips and a tremendous emphasis on HOW non humans would communicate.

[Tom Cruz]

Yeah the deepest points in the ocean are my new favorite curiosity right now. It's like an alien world but right here on Earth.

[Early Cuyler]

@Tom Cruz There's a channel called EVNautilus that livestreams subs diving way down to look at the critters

[jussi tikkuri]

@Tom Cruz Scientists here on Earth know more about the Moon and Mars than we know about our own oceans which seems so ridiculous to me on several different levels.

[GPF SexEE x xx]

the fact we even have a place in our ocean called "The Abyss" and "The Trenches" is horrifying, but amazing

[Daley Halter]

This video was very informative and well done.

[Jayden B]

Hey, watching my hives inflammation fade day after day until they completely vanished was such a relief, I went with what I pointed out and within the first 10 days or so the urticaria/angioedema was barely visible! I just go'ogled the latest by Shane Zormander and after 20 days my skin has never been healthier!

[Dried vegetable]

This captures are insane.Thank you so much for showing me this.

[SleepSteward]

Something I find quite funny to think about is if the Greenland Sharks had some sort of child protection laws as we do. For most Western countries its 16-18 years old. These guys can't reproduce until around 120-150 years of age. "Sir, that shark is only 96 years old!" Explaining it made it less funny but I still find it quite amusing 😅

[Spectrickx]

The deep sea has got to be one of the most fascinating things to me. From the lnexplainable creatures to the miraculous beings, the deep sea is a treasure trove of fun facts.

[Steph Meloche]

This is why Subnautica was such a hit video game!!

[Vaughen_Gogh_Away]

Bro this video is amazing, it's so easy to get informational videos about this stuff that just can't keep my attention but the pacing was amazingly easy to listen to. As somebody with auditory processing issues and ADHD, that's a feat fr.

[Santiago Lattuf]

It's absolutely insane how little we know about the sea

[wilson from dst]

You deserve a subscribe from me this was so informative and interesting. narration is great.

[Parts and Neighbor]

My brother is a giant overweight deep sea squid... so glad to see a nicely done video documentary about it.

[Stellar Roots]

If those deep sea creatures are huge in size, imagine how much bigger they'll get if they were brought from kilometers worth of water pressure to to surface, where they'll expand even more due to decompression!

[Young Lee]

The deep sea is such a magical place. It’s so cool that some of them could live up to 500 years. The Greenland shark is by far the most interesting personally. Great video!

[Mr Fake]

The place is Terrifying

[Björn copperside]

magical place? you make it sound like disney, its probably the closest thing we have to hell LOL

[Spock Of Dune]

Bravo ! Nicely done. BTW I loved the bit with the "in pitch black darkness at 2C with crustaceans in my eyeballs for 500 years"

[Turtle Turtle]

Whats crazy about all this is that we are able to go to space and to the deep sea even if it's only through our technology. How many other creatures can survive in these places whether they thrive or not they can still be there alive and come back.

[Zona 88]

It's strange, the difficulty of food and the extreme environment actually makes them grow big and live long

[Nevers Scortch]

Really great video, I learned alot and you're very well spoken

[Google User]

Breathtaking. One other thing that could be worth exploring: Oxygen availability at different depths.

[The decaying watcher]

I've always found giant sea creatures interesting, I remember the first time I saw an angel shark I was filled with so much glee at how weird, cool or just straight up horrifying, I want to become a marine biologist so I can be close to and study something so alien yet familiar to me, it feels me with a deep sense of foreboding curiosity.

[Music Study]

Thanks for such insightful video on klieber's law.... Due to this Russian people in Siberia (one of the coldest region on earth) have average height 177- 180 cm And same goes for African countries... Both of these regions have extreme temperatures but people here grow a lot taller

[DittyTheDitto]

Just wanna give a shoutout to the cameraman who managed to record these submarines at those depths.

[Ali a333aa346]

Just imagine being stuck there in the dark not knowing what is coming or what is around you that is absoulutley terrifying !

[Ariel Plaza]

Marine Snow may be the most common but there are other sources of energy/nutrients in the deep in the form of geothermal vents and cold seeps. Geothermals are fairly well known, essentially underwater volcanoes, and will form dense colonies of creatures around them. Less well known are cold seeps, where methane and other natural gasses are being releases, which creates communities of organisms who are adapted to make use of it.

[Cody Ashline]

Can't believe I am just now finding your channel. Love the videos so far.

[Davethreshold]

That was INCREDIBLE! Years ago, Time Magazine showed a newly discovered species, toward the bottom of the ocean floor. It lived in thousands of pounds of pressure next to a BOILING natural petroleum vent! That environment would kill any Human in a second. Right then I knew that life NOT as we know it is capable of existing elsewhere. Two films that demonstrate that are The Andromeda Strain, (1971) and much more recently, Annihilation (2018). Thank you for this one!

[Axis Church Devotee]

Life uh, finds a way.

[Elite Metro Cop]

@Axis Church Devotee the way of the drider and hog is the only way. HOOOOOOOOOOOGGGGGGGG DRIIIIIIIIIIIIIIIIIIIIDAAAAAA

[virtual-adam]

Annihilation is a great movie. The part near the end when the alien changes form is a real work of art.

[Davethreshold]

@virtual-adam YES! And the entire thing was a new type of Alien. It was not necessarily here to harm us. It just, "was." Have you seen Andromeda Strain? kzbin.info/www/bejne/j37FhKOkobSCqqc

[Early Cuyler]

I will fight to the day I die that Annihilation was a stupid movie with stupid characters. I cannot comprehend how sane or competent people could have caused the events that led up to the beginning of the movie. I can think of 15 ways to send that Abhorrent Space Alien back to its Disgusting Alien God without setting a Single Human Foot inside the Zone.

[LargeBlueCircle]

I wonder if the oceans of europa would hold similar wonders, or without the Epipalagic zone, there isnt enough food filtering down from the surface to maintain the layers of ecology, and all we would find were tiny and micro organisms around heat vents.

[Rom Shalfey]

Me as a person who ran to another country because of “news from the world”. Was laughing from joke to be like a Greenland shark for a while. Great content ❤

[Longina Makumbe]

the way she seemlessly transitioned from greenland sharks to morning news and twitter,legend!
